Abstract
Long equatorial waves recently discovered in the Pacific Ocean on satellite photographs are being linked to oscillations in sea level at Fanning Island and to the oscillatory trajectory of a drifting buoy. The drift pattern of the buoy suggests that lateral oscillations of the Equatorial Countercurrent with a period of about 34 days are responsible for the observed variations of sea level.
